Subject: [Qemu-devel] [PATCH v2 0/2] Integrating qemu to Linux Perf
Date: Fri, 30 Aug 2019 09:19:01 -0300 [thread overview]
Message-ID: <20190830121903.17585-1-vandersonmr2@gmail.com> (raw)
This patch is part of Google Summer of Code (GSoC) 2019.
More about the project can be found in:
https://wiki.qemu.org/Internships/ProjectIdeas/TCGCodeQuality
This adds --perf command-line option to dump Linux Perf
jitdump files. These files are used to enhant Perf report
and to be able to analyze and dump JITed code with perf.
Example of use:
perf record -k 1 qemu-x86_64 -perf ./a.out
perf inject -j -i perf.data -o perf.data.jitted
perf report -i perf.data.jitted
